An American tourist was lunching in a restaurant in China whose speciality was duck. The waiter explained each dish as he brought it to the table: “This is the breast of the duck. This is the leg of the duck. This is the wing of the duck.
Then came a dish that the American knew was chicken. He waited for an explanation. Silence. “Well,” he finally asked. “What's this?” “It's a friend of the duck.” said the waiter.
